You can double tap anywhere on the AirPods to activate a customisable command as they have accelerometers built in. By default, when you double tap, this activates Siri. But you can change this on individual AirPods to Pause, Next Song, Previous Song or turn off the feature completely. So, for example, you can set it up so if you double tap your Left AirPod, it pauses the music that’s playing and when you double tap the right AirPod, it skips the track, but this is completely up to you.

These new AirPods have a faster connection speed and lower latency compared to the first gen AirPods. The new AirPods also have the new "Hey Siri" feature allowing you to say "Hey Siri" to you AirPods to activate Siri.

I don’t think my phone will make it to ios 13 so do I need to consistently have the latest ios or can I just have ios 12.2 and be fine to buy these and continue to use them. even when my phone no longer gets software updates will I be able to use them.
